This invention relates to surface water craft of the kind having hollow keels, and has for its object to furnish such craft with cabin accommodation in which the requisite avoid the need of any superstructure above 7 the deck and natural gunwale of the hull.

According to the presentinvention the deck of the hull forms the roof of the cabin, the

tively narrow hollow keel that communicates with the interior of the hull and is left uncovered between the cabin bulkheads so that the hollow keel forms a central fore and aftcorridor through the cabin, in which latter sleeping berths, lockers and the like are arranged in the hull proper on each side of the hollow keel.

The hollow keel is of rectangular cross section amidships and is stream lined towards each end according to the design of the hull, and may either extend the full length of the hull or terminate at any required distance under or towards the stern quarter thereof.

The parts of the hollow keel which extend fore and aft of the cabin may be decked over and utilized in known manner for theaccommodation of a motor engine and its driving gears and control, and also petrol and other fuel, stores, ballast or the like. 7

The present invention is illustrated by way of example in the accompanying drawings wherein similar references indicate like parts.

Figure 1 is a side View partly broken away and Figure 2 a plan in half section of a'ten metre cabin cruiser provided with a motor engine and constructed in accordance with the present invention.

Figures 3 to 6 are cross-sections on the lines II-II, IIIIII, IVIV, VV and VIVI (Figure 1).

As illustrated in the drawings the hull 1 is built upon the rectangular hollow keel 2 which serves to accommodate the motor, fuel and other heavy stores or gear, and is provided with a deck a which. in accordance with the present invention forms the roof of a cabin 7) arranged forward of amiships between transverse-bulkheads c and (Z that are continued into the hollow keel as indicated at c and d, respectively. 1 i The requisite head room within'the-cabin uncovered between the cabin bulkheads so that the bottom'3 of the keel forms the floor wmet- =1- is provided .by thehollow keel which is left 5 of the cabin and provides a central corridor between bunks or sofas 6 arranged in the hull iatload-water level, jtheydepth of the keel ,beingIsufiicient to enable,slabs offlead or other suitable ballast 1 "laid along the bottom'thereof while leavingample standing room within the cabin.

Lockersm are, arranged in any -convenient manner beneath the bunks or sofas e which latter may be hinged at n '(see Figure 4;) to afford easy access to the lockers m, orthe latter may be furnished with hinged falls or v sliding doors, or withidrawers. or the like arranged in any convenient manner in the inboard sections 2 of the hollow keel 2.

The aft bulkhead'c is provided with a door 7 having the same Width as the hollow keel 2, which door gives access to the cabin from the cockpit 9, steps it being arranged inside the cabin on the bottom part 0 of the bulkhead 0 to facilitate entry into and exit from the cabin, while a'compartment c or continuation of the cabin forward of the bulkhead cl provides accommodation for a cooking galley, lavatory. etc.

The hatchway k is arranged in'the deck a to give access to the forward compartment 2', while if desired a narrow doorway may be arranged in the bulkhead d to form a communication between the cabin b and the forward compartment 2'. v

The open cockpit g is provided as usual with a seat 21 to accommodate the passengers and crew, while the motor engine, driving gear, petrol tanks and soforth are housed iao sure above the'gunwa'le, the an -in centre of gravity of the vessel being consequently kept I appreciably lower than in vessels of ordinary construction, while the requisite sail-area can be carried by shorter and lighter masts with consequent lowering of the centre of v "jwind effort, thus greatly enhancing the" gen- 7 eral's-eaiworthiness ofthe vessel lowingft o'fits'y 1 increased "stabi'1ity,fsafet and "ease of'handling under power or sai Iclairn:'
